U Turns

Question

Hello,
I am having difficulty with this aspect.  I am planning school bus routes and I absolutely don't want any U-turns.  Eventhough I have specified "Not Allowed" in the Layer Property Analysis Settings, the program does not obey this constraint.  I have a bus stop in the middle of a street (not at a junction and the routing wants me to make a U-turn right there!)  I have tried "Allowed only at intersections and/Dead Ends" options and it still does not work. What am I doing wrong?

Thank you.

You need to change the curb approach property of the individual stops to say "No U-Turn".
You can do it for all of them by opening the Stops Attribute table and then using the field calculator to set the curb approach to the value 3. And then re-solve. You can read more about curb approach here:
